A crown lengthening procedure is designed to reshape the gums at the base of the desired tooth. Its purpose is to expose additional tooth surface and if necessary adjust the bone level. There are a number of dental conditions that need restorations requiring this procedure. Most common is severe tooth decay below the gum line. Another is when a tooth has fractured and broken off beneath the existing gum line.
Restoring Damaged Teeth
Crown lengthening can play a critical role in the restoration of damaged teeth. Severe tooth decay or injury may result in teeth broken or destroyed below the gum line. By exposing more of the tooth, the crown lengthening procedure provides a stable base for the final tooth restoration.
Crown lengthening is also frequently used to support cosmetic dental procedures. It is especially useful in cases where the gum extends too far down the length of the teeth causing them to appear unnaturally short. This can also increase their vulnerability to periodontal disease. Removal of this extra gum tissue can restore a natural look and thus improve a smile.
Crown lengthening is performed by your periodontist under local anesthesia. This can be combined with sedation for those patients who desire it. The selected area of the gums is reduced and contoured through the removal of small amounts of tissue. The goal is to lengthen the appropriate teeth and create greater symmetry at the gum line.
